- How does this MOSFET based motor driver designed work
The Mosfet is acting like a switch, the PWM output of the arduino should not be loaded with more than about 10mA, so for a tiny current spike at every switch on switch off change, the mosfet can potentially switch 10's of amps
- Transconductance of a MOSFET - Electrical Engineering Stack Exchange
I am trying to understand this formula to find the transconductance of a MOSFET transistor, but I am not getting the passage from the second to the third line What happened there? Thank you
- transistors - Short in MOSFET between Gate and Drain - Electrical . . .
When The Drain and Gate of a MOSFET are connected together, A two-terminal device known as a ''diode-connected transistor'' results if drain and gate is shorted then MOS will behave as a diode connected load and it will never go to triode region and can be used as resistive load offering a resistance equal to 1 gm if drain and source is shorted then MOS capacitor in which SiO2 will behave as
- mosfet - Solenoid driver circuit with peak hold - Electrical . . .
That driver can be a small relay, a low-side BJT or mosfet driver, etc It just needs to hard-switch, our circuit will take care of switching from the 12V supply to the hold supply
- mosfet - In an NMOS, does current flow from source to drain or vice . . .
Conventional current flows from Drain to Source in an N Channel MOSFET The arrow shows body diode direction in a MOSFET with a parasitic diode between source and drain via the substrate
- MOSFET symbol - what is the correct symbol - Electrical Engineering . . .
I've been on this site now a couple of months and I notice various symbols used for MOSFETs What is the preferred symbol for an N Channel MOSFET and why?
- Do MOSFETs have a diode built into them?
For single MOSFET circuits driving an inductive load, the body-diode will NOT work as a replacement for a flyback diode as it conducts in the wrong direction Consider for example an N-channel MOSFET as a low-side driver for a solenoid When the MOSFET turns off, the voltage spike at the drain will be positive
- How are MOSFET gate capacitances (Cgs, Cgd) calculated?
6 Your equations are approximations to the capacitance seen between G-D and G-S of a mosfet in different regions of operation and they are derived based on the physical characteristics of the mosfet Keep in mind that the physical mosfet is a symmetric device
